an 86 951 is 217 hp according to kevins page http://www.connact.com/~kgross/FAQ/944faq02.html and weighs about 20 pounds less than a 931 (same page), i see no reason why with a little work a 931 cant run with a 951. in fact i have seen it happen, but i cant account for the condition of the 951 so i dont really count it.

951's are awesome cars, but penny for penny, the 931 is a much less expensive option and has more low $$ upgrade potential in my humble opinion._________________Eric

Hey, chill out ok. Nothing bad has happened. Just read the complete post and let your enthusiasm take a back seat. Now I like your CGT rep, but I doubt it could live with any of my old 932's. I'm only just touching those babies with my 3litre16V motors....I have welded in 924 engine mounts into my 944 chassis so don't ever believe that I don't know the 931's possibilities.

I think you have a great point. But you too are falling into the same trap! the comparison is between STOCK applications!

Assuming they were either both US or both Euro and if for some strange reason I could not mod either car (931 or 944) then yes I would choose the 944. The Porsche designed lump is the better engine and not having a turbo would in the long run be easier to maintain and probably longer lived. In this context its really a no brainer and a clear reason why the 944 was such a great seller._________________1981 931 CGT replica, OEM CGT intercooler, .8 BAR WG spring, GTS Headlights, Innovative Wide band A/F, A/C delete, 16" Fuchs, Weltmeister 200lb lowering springs, Bilstein HDs front, Koni Sport rears.

Accepted and I apologize as well for being such a prick in one of my responses, I could have easily made my point with out calling you an "island monkey" _________________1981 931 CGT replica, OEM CGT intercooler, .8 BAR WG spring, GTS Headlights, Innovative Wide band A/F, A/C delete, 16" Fuchs, Weltmeister 200lb lowering springs, Bilstein HDs front, Koni Sport rears.

The point of this whole discussion is that GRM made the comparison of the 931 to the 944. Bringing up a 924NA or a 951, while interesting, is orthogonal to the discussion at hand.

And who said the comparison had to be stock-to-stock comparison? Plain and simple, a 931 offers more bang for the buck in terms of initial cost, cost to maintain, and cost to modify than the 944, beats it hands down in all three comparisons.

As for reliability, I can only comment on my experience. My 924S broke down and stranded me or my son more times in the 9 months I owned it than my three running 931s, my 928 and my 924 NA combined. The only time I have EVER been stranded by a 931 was in the first month of ownership before I had opportunity to do my own preventive maintenance.

The 924S also cost me more money than any one of my other cars to get running into reliable, saleable condition, and YES, that includes the 928 with full FOES service. Now bear in mind, this car had full documented history and was a 2-owner car before I got it, maintained by an absolutely anal Porsche guy, local PCA member. But the car was at about the 100K mark in mileage, and a whole bunch of things started going wrong all at once. Took me 9 months to sort out. None of my other 924s took nearly that long or caused nearly the frustration.

I realize this is only one example, but as I said, all of my 931s have been way more reliable.

As for maintenance intervals, I unloaded the 924S as fast as I could, so I didn't own it long enough to accumulate the miles required to redo FOES. As for the 928, because it's not an interference motor, I have not done FOES every 36 months. I did it within the first year of owning it, and have put less than 5K miles per year on it since. Given the risk vs. the cost on that car, I'm perfectly happy to drive it until the belt breaks since it won't damage the motor. If I had a 2.5L 924S/944 or a 32V 928, I wouldn't be so cavalier about it._________________15 981 GTS | 88 924S SE | 82 931 Holbert | 82 931 Rallye | 81 937 | 81 Euro 931 | 81 Weissach | 80 US 928 | 80 US 931 '941' | 80 US 931 | 80 931 GTR | 79 Sebring | 78 D-Prod Replica | 78 w/D-Prod kit | 78 Poli-Form | 78 Limited Edition | 77 Martini
